1·The abortive pollen was small than normal pollen and it's microstructure was abnormal.

败育花粉的特征是花粉粒小，超微结构异常。

2·The effects of temperature on the bagged self seed and the abortive pollen types of indica TGMS rice line 2301s were studied by sowing on different dates in 1999 and 2000.

1999年和2000年分期播栽试验，研究了温度对籼型温敏核不育系2301s自交不育度和花粉败育类型的影响。

3·Honglian (HL) type CMS lines (Indica) differed from wild abortive (WA) type CMS lines (Indica) not only in characteristic of abortive pollen but also in restoring and maintaining abilities.

籼稻红莲型(HL)不育系和野败(wa)型不育系除花粉败育的特征不同外，两者还具有不同的恢、保特性。

4·Abortive shapes of pollen grains were in varied forms, such as irregular, round and spindle etc.

花粉粒败育形态多种多样，有不规则形，梭形，圆形等。

5·With the rise of temperature , the development of pollen speeded up, the abortive trend of stamen increased.

随着温度的升高，花粉粒发育速度加快，雄蕊败育趋势增加。
